Question

Please help Me!!!!!

Divide the following polynomial, then place the answer in the proper location on the grid. Write your answer in order of descending powers of y.

(y 3 - 4y 2 + 7y - 6) (y - 2)

Answer 1

are you familiar with polynomial division?

Answer 2

no

Answer 3

well then we'll have to start from the beginning

Answer 4

ok i need all the help i can get

Answer 5

what is y^3/y ?

Answer 6

im not really sure

Answer 7

y^3 divided by y = y^2 OK?

Answer 8

ok

Answer 9

so whats the next step @alekos

Answer 10

so now we have the following

Answer 11

ok

Answer 12

so now we have y^2 on the top above the y^3
now what is y^2(y-2)

Answer 13

would that be mutiplication?

Answer 14

yep

Answer 15

so so would lthat be 2*-2?

Answer 16

no its

y^2(y-2) = y(y^2) - 2(y^2)

so what does that come out to?

Answer 17

2y^2

Answer 18

no its y^3 - 2y^2 OK?

Answer 19

ok

Answer 20

so now we have

Answer 21

we place this result underneath the original polynomial starting from the first term.
Now we subtract the first 2 terms from each other
i.e. y^3 - 4y^2 - (y^3 -2y^2) ?

Answer 22

ok

Answer 23

your turn

Answer 24

y-2y

Answer 25

no its -2y^2, can you see that?

Answer 26

not really im confused on this part

Answer 27

(y^3 - 4y^2) - (y^3 - 2y^2) = (y^3 - y^3) - 4y^2 + 2y^2
= -2y^2

Answer 28

oh ok i see now

Answer 29

OK, next step

Answer 30

ok

Answer 31

Just like a normal long division. you see?

Answer 32

yeah

Answer 33

Now we divide -2y^2 by the y from the (y-2) divisor
what do we get?

Answer 34

im not sure

Answer 35

im completely lost on this

Answer 36

_2y^2/y = ?

Answer 37

yeah you can do it

Answer 38

wouldnt that just be y^2

Answer 39

no try again

-2y^2 divided by y = ?

Answer 40

i dont know

Answer 41

if you're struggling with this, then polynomial long division will be like climbing a mountain!

lets start with this

\[\frac{ y^{2} }{ y } = y\]

Answer 42

so what is

\[\frac{ -2y ^{2}{} }{ y } = ?\]

Answer 43

-y^2

Answer 44

we're not getting anywhere unfortunately.
You need some serious help with algebra.
I would love to help you further but we need to get the algebra sorted first.
I suppose your in the US, is that right?

Answer 45

yup and yeah i know i suck at algebra

Answer 46

you need to get the algebra sorted first before you can even hope to solve polynomial long division problems. Do you have a local tutor?
I would love to help you out but I'm in the middle east and I tutor high school students every week.
I don't know, maybe we can do a skype tutoring session or something?

Answer 47

i dont have skype

Answer 48

I take it you have a PC so does it have a microphone/speaker and/or camera?

Answer 49

no i dont have a laptop just a desk top

Answer 50

OK, I see. That makes it a little difficult. Maybe I can send you some algebra problems then via email with a little theory and some examples?

Answer 51

ok thanks
